v0.9.0

Features:

• Add .options.enablePayloadHashCalculation in common configuration: this flag increase the security actually calculating the hash of the payload before signature verification.

  Use it with caution as it increase the security at the cost of decreasing the performance due to an intermediate place is needed during this operation. We selected disk instead of memory as it's cheaper solution, and include memory in future releases
